O Brasil situa-se, no início da década de 2010, dentro de um sistema econômico mundial que apresenta características de ampla globalização dos mercados e alta competitividade das organizações que compõe esse sistema, e que sinalizam a necessidade de profissionais que sejam agentes de mudança nesses contextos dinâmicos e repletos de desafios. Na maioria dos países, a maturidade do sistema de inovação está ligada ao investimento em Pesquisa e Desenvolvimento (P&D) e ao volume de geração de Propriedade Intelectual (PI). O Brasil, apesar de apresentar um Produto Interno Bruto (PIB) concentrado nos setores de agropecuária e de serviços, revela um nível de inovação gerado pelo setor produtivo e o seu consequente investimento em P&D muito baixos em comparação com a evolução desse mesmo PIB, denotando com isso que as empresas buscam, em seus países de origem, soluções já desenvolvidas e patenteadas para seu desenvolvimento ou procuram transferir a responsabilidade de produzir registros e patentes de inovações à academia. A integração da cultura acadêmica com a cultura empresarial é capaz de gerar benefícios mútuos, melhorando a competitividade do país; em outras palavras, é uma maneira de transformar o conhecimento em riqueza. Este trabalho relacionando os conceitos ensino-pesquisa e prática empresarial pretende estudar, sob o enfoque da realidade apresentada pelos Planos Estratégicos Regionais (PER) da Região do Grande ABC Paulista e das diretrizes do Plano Nacional de Pós-Graduação 2011-2020 (PNPG 2011-2020), o processo de integração do conhecimento científico existente entre as Entidades Empresariais (E-E) e as Universidades dessa mesma região. Através da metodologia de pesquisa de estudo de caso, analisaram-se as estratégias propostas pelas universidades e a prática do setor empresarial e as possíveis barreiras apontadas como restrições às interações entre eles. Nosso estudo enfocou a análise da relação entre esses dois atores e apontou as principais barreiras para a otimização dessa parceria, tais como o acesso a recursos, o aumento da competitividade via aumento da credibilidade na relação Universidade Empresa (U-E), o reconhecimento das realidades regionais e o latente descompasso entre o pensamento acadêmico e a realidade empresarial. Além disso, constatou-se a necessidade de uma mais ampla discussão, disseminação e implementação dos documentos setoriais, regionais e nacionais que regulam, esclarecem e fornecem bases estratégicas para o desenvolvimento da relação U-E, como forma de otimização do processo de transformação do conhecimento em riqueza social.

O Distrito de Aveiro caracteriza-se pelo seu extenso tecido empresarial, cada vez mais consciente da importância da internacionalização. Os dados recolhidos e posteriormente analisados, permitiram concluir que entidades como a AIDA (Associações Empresariais) devem promover a internacionalização de PME com um reduzido grau de internacionalização. Desta forma, este tipo de entidades aumentarão o alcance de PMEs ao nível da divulgação e acesso facilitado a informações sobre apoios à internacionalização, assim como a informações sobre os diversos mercados de interesse para as PME. O presente trabalho também estudou o impacto de atributos de CEOs na internacionalização de PMEs. Para o seu desenvolvimento foi utilizada uma amostra de três Micro, Pequenas e Médias Empresas do Distrito de Aveiro. Os resultados, que foram obtidos pela metodologia qualitativa através de entrevistas semiestruturadas e outras informações recolhidas nas respetivas empresas, mostram evidência que: os atributos dos CEOs analisados (Idade, Nível Educacional e Experiência Internacional) relacionados com o grau de internacionalização das empresas, permitiram uma validação das hipóteses colocadas na revisão de literatura. Conclui-se, através deste estudo exploratório, que a idade [mais avançada] do CEO tem um impacto negativo na internacionalização de uma PME; que o nível educacional [mais elevado] do CEO tem um impacto positivo na internacionalização de uma PME; e, ainda, que a [maior] experiência internacional do CEO tem um impacto positivo na internacionalização de uma PME.

The artificial lifting of oil is needed when the pressure of the reservoir is not high enough so that the fluid contained in it can reach the surface spontaneously. Thus the increase in energy supplies artificial or additional fluid integral to the well to come to the surface. The rod pump is the artificial lift method most used in the world and the dynamometer card (surface and down-hole) is the best tool for the analysis of a well equipped with such method. A computational method using Artificial Neural Networks MLP was and developed using pre-established patterns, based on its geometry, the downhole card are used for training the network and then the network provides the knowledge for classification of new cards, allows the fails diagnose in the system and operation conditions of the lifting system. These routines could be integrated to a supervisory system that collects the cards to be analyzed

The primary cementing is an important step in the oilwell drilling process, ensuring the mechanical stability of the well and the hydraulic isolation between casing and formation. For slurries to meet the requirements for application in a certain well, some care in the project should be taken into account to obtain a cement paste with the proper composition. In most cases, it is necessary to add chemicals to the cement to modify its properties, according to the operation conditions and thus obtain slurries that can move inside the jacket providing a good displacement to the interest area. New technologies of preparation and use of chemicals and modernization of technological standards in the construction industry have resulted in the development of new chemical additives for optimizing the properties of building materials. Products such as polycarboxylate superplasticizers provide improved fluidity and cohesion of the cement grains, in addition to improving the dispersion with respect to slurries without additives. This study aimed at adapting chemical additives used in civil construction to be used use in oilwell cement slurries systems, using Portland cement CPP-Special Class as the hydraulic binder. The chemical additives classified as defoamer, dispersant, fluid loss controller and retarder were characterized by infrared absorption spectroscopy, thermogravimetric analyses and technological tests set by the API (American Petroleum Institute). These additives showed satisfactory results for its application in cement slurries systems for oil wells. The silicone-based defoamer promoted the reduction of air bubbles incorporated during the stirring of the slurries. The dispersant significantly reduced the rheological parameters of the systems studied. The tests performed with the fluid loss controller and the retarder also resulted in suitable properties for application as chemical additives in cement slurries

In the last decades, the oil, gas and petrochemical industries have registered a series of huge accidents. Influenced by this context, companies have felt the necessity of engaging themselves in processes to protect the external environment, which can be understood as an ecological concern. In the particular case of the nuclear industry, sustainable education and training, which depend too much on the quality and applicability of the knowledge base, have been considered key points on the safely application of this energy source. As a consequence, this research was motivated by the use of the ontology concept as a tool to improve the knowledge management in a refinery, through the representation of a fuel gas sweetening plant, mixing many pieces of information associated with its normal operation mode. In terms of methodology, this research can be classified as an applied and descriptive research, where many pieces of information were analysed, classified and interpreted to create the ontology of a real plant. The DEA plant modeling was performed according to its process flow diagram, piping and instrumentation diagrams, descriptive documents of its normal operation mode, and the list of all the alarms associated to the instruments, which were complemented by a non-structured interview with a specialist in that plant operation. The ontology was verified by comparing its descriptive diagrams with the original plant documents and discussing with other members of the researchers group. All the concepts applied in this research can be expanded to represent other plants in the same refinery or even in other kind of industry. An ontology can be considered a knowledge base that, because of its formal representation nature, can be applied as one of the elements to develop tools to navigate through the plant, simulate its behavior, diagnose faults, among other possibilities

In the Hydrocarbon exploration activities, the great enigma is the location of the deposits. Great efforts are undertaken in an attempt to better identify them, locate them and at the same time, enhance cost-effectiveness relationship of extraction of oil. Seismic methods are the most widely used because they are indirect, i.e., probing the subsurface layers without invading them. Seismogram is the representation of the Earth s interior and its structures through a conveniently disposed arrangement of the data obtained by seismic reflection. A major problem in this representation is the intensity and variety of present noise in the seismogram, as the surface bearing noise that contaminates the relevant signals, and may mask the desired information, brought by waves scattered in deeper regions of the geological layers. It was developed a tool to suppress these noises based on wavelet transform 1D and 2D. The Java language program makes the separation of seismic images considering the directions (horizontal, vertical, mixed or local) and bands of wavelengths that form these images, using the Daubechies Wavelets, Auto-resolution and Tensor Product of wavelet bases. Besides, it was developed the option in a single image, using the tensor product of two-dimensional wavelets or one-wavelet tensor product by identities. In the latter case, we have the wavelet decomposition in a two dimensional signal in a single direction. This decomposition has allowed to lengthen a certain direction the two-dimensional Wavelets, correcting the effects of scales by applying Auto-resolutions. In other words, it has been improved the treatment of a seismic image using 1D wavelet and 2D wavelet at different stages of Auto-resolution. It was also implemented improvements in the display of images associated with breakdowns in each Auto-resolution, facilitating the choices of images with the signals of interest for image reconstruction without noise. The program was tested with real data and the results were good

The Compound Portland cements are commonly used in construction, among them stand out the CPII-Z, CPII-F and CPIV. These types of cement have limited application on oil well cementing, having its compositional characteristics focused specifically to construction, as cement for use in oil wells has greater complexity and properties covering the specific needs for each well to be coated. For operations of oil wells cementing are used Portland cements designed specifically for this purpose. The American Petroleum Institute (API) classifies cements into classes designated by letters A to J. In the petroleum industry, often it is used Class G cement, which is cement that meets all requirements needed for cement from classes A to E. According to the scenario described above, this paper aims to present a credible alternative to apply the compound cements in the oil industry due to the large availability of this cement in relation to oil well cements. The cements were micro structurally characterized by XRF, XRD and SEM tests, both in its anhydrous and hydrated state. Later technological tests were conducted to determine the limits set by the NBR 9831. Among the compound cements studied, the CPII-Z showed satisfactory properties for use in primary and secondary operations of oil wells up to 1200 meters cementing

The demand for alternative sources of energy drives the technological development so that many fuels and energy conversion processes before judged as inadequate or even non-viable, are now competing fuels and so-called traditional processes. Thus, biomass plays an important role and is considered one of the sources of renewable energy most important of our planet. Biomass accounts for 29.2% of all renewable energy sources. The share of biomass energy from Brazil in the OIE is 13.6%, well above the world average of participation. Various types of pyrolysis processes have been studied in recent years, highlighting the process of fast pyrolysis of biomass to obtain bio-oil. The continuous fast pyrolysis, the most investigated and improved are the fluidized bed and ablative, but is being studied and developed other types in order to obtain Bio-oil a better quality, higher productivity, lower energy consumption, increased stability and process reliability and lower production cost. The stability of the product bio-oil is fundamental to designing consumer devices such as burners, engines and turbines. This study was motivated to produce Bio-oil, through the conversion of plant biomass or the use of its industrial and agricultural waste, presenting an alternative proposal for thermochemical pyrolysis process, taking advantage of particle dynamics in the rotating bed that favors the right gas-solid contact and heat transfer and mass. The pyrolyser designed to operate in a continuous process, a feeder containing two stages, a divisive system of biomass integrated with a tab of coal fines and a system of condensing steam pyrolytic. The prototype has been tested with sawdust, using a complete experimental design on two levels to investigate the sensitivity of factors: the process temperature, gas flow drag and spin speed compared to the mass yield of bio-oil. The best result was obtained in the condition of 570 oC, 25 Hz and 200 cm3/min, temperature being the parameter of greatest significance. The mass balance of the elementary stages presented in the order of 20% and 37% liquid pyrolytic carbon. We determined the properties of liquid and solid products of pyrolysis as density, viscosity, pH, PCI, and the composition characterized by chemical analysis, revealing the composition and properties of a Bio-oil.

Since the beginning of the National Program for Production and Use of Biodiesel in Brazil, in 2004, different raw materials were evaluated for biodiesel production, trying to combine the agricultural diversity of the country to the desire to reduce production coasts. To determine the chemical composition of biodiesel produced from common vegetables oils, international methods have been used widely in Brazil. However, for analyzing biodiesel samples produced from some alternative raw materials analytical problems have been detected. That was the case of biodiesel from castor oil. Due the need to overcome these problems, new methodologies were developed using different chromatographic columns, standards and quantitative methods. The priority was simplifying the equipment configuration, realizing faster analyses, reducing the costs and facilitating the routine of biodiesel research and production laboratories. For quantifying free glycerin, the ethylene glycol was used in instead of 1,2,4-butanetriol, without loss of quality results. The ethylene glycol is a cheaper and easier standard. For methanol analyses the headspace was not used and the cost of the equipment used was lower. A detailed determination of the esters helped the deeper knowledge of the biodiesel composition. The report of the experiments and conclusions of the research that resulted in the development of alternative methods for quality control of the composition of the biodiesel produced in Brazil, a country with considerable variability of species in agriculture, are the goals of this thesis and are reported in the following pages
